Description

Multifunctional thoracic cavity puncturing device

The utility model relates to a kind of medical apparatus and instruments, what particularly relate to a kind ofly treats the multi-functional thoracentesis needle device that pneumothorax, hydropneumothorax patient are used always.

Pneumothorax patient thoracic-puncture needle puncture commonly used, closed drainage of pleural cavity aerofluxus treatment.The thoracic-puncture needle that the intrathoracic surgery of China is commonly used is made up of the nook closing member in conduit, the conduit of packing into, drainage tube etc. at present, and the nook closing member front portion mostly is prismatic, and in order to thrusting, afterbody has handle, and is easy to operate.During work, after point of puncture sterilization local anaesthesia, cut skin, separate subcutaneous tissue and thoracic wall muscle to parietal pleura, the thoracic-puncture needle that will have nook closing member thrusts the thoracic cavity, takes out nook closing member, puts into drainage tube, takes out sleeve pipe again.Otch is bigger, and separation or cut-out muscle fiber, damage weigh, and drainage tube is less, and drainage tube and pin base portion joint join.Draw in the front, and drainage tube is vertical with thoracic wall, easily distortion of drainage tube, pressurized or stopped up by secretions, blood clot that to cause aerofluxus not smooth.It is fixing that drainage tube adopts rubberized fabric adhere to fix or be sutured on the skin more, causes fixing not firmly and move back pipe, produces subcutaneous emphysema, even treatment failure or formality trouble.

In view of above reason, the purpose of this utility model is for a kind of simple and safe operation is provided.Disposable importing.Can be according to patient's thoracic wall thickness adjusted depth of needle, the aerofluxus discharge opeing is unobstructed, pressure measurement is convenient, and skin incision is little, fix tightly, be applicable to intrathoracic, the surgery of hospitals at different levels and the clinical treatment pneumothorax patient's of tuberculosis section multi-functional thoracentesis needle device.

The utility model is achieved like this: this utility model is by thoracic-puncture needle, pectoral girdle is formed, thoracic-puncture needle comprises the hollow nook closing member, conduit, three-way valve, fixing head, three-way valve comprises valve body, the nook closing member import, catheter adapter, exhaust joint, be loaded on the controlling organization that can control airflow direction on the valve body, the front end side of conduit is porose, conduit is connected in the catheter adapter, the hollow nook closing member can pass the nook closing member import, catheter adapter, conduit is (referring to Fig. 1, Fig. 6), pectoral girdle is by the pectoral girdle hook, band is formed, and links closely with hook eye on the fixing head and make pectoral girdle connect (referring to Fig. 2) with thoracic-puncture needle in the two ends of pectoral girdle hook.

The front end of the hollow nook closing member in this utility model is shaped as taper (referring to Fig. 3), the rear end is an indication joint (referring to Fig. 1), one end of rubber tube connects with indicator sub, the other end connects with water-sealed drainage bottle, after the hollow nook closing member thrusts pleural space, have blister to overflow the water surface in the water-sealed drainage bottle, the expression thoracic-puncture needle has entered the thoracic cavity.

Controlling organization in this utility model is by sliding pin, elastic ring is formed (referring to Fig. 1, Fig. 5), through hole is arranged on the sliding pin, groove, the sliding pin groove is arranged on the valve body of three-way valve, have groove on around the valve body, sliding pin is contained in the sliding pin groove and can slides in the sliding pin groove, elastic ring is contained in the groove and the groove around the valve body of sliding pin one end, the control sliding pin skids off the sliding pin groove or sliding pin is resetted, the control airflow direction, the hollow nook closing member can pass the nook closing member import, through hole on the sliding pin, catheter adapter and enter (this moment, the exhaust joint mouth blocked) among the conduit, extract the hollow nook closing member out, sliding pin under the effect of elastic ring, reset (this moment, the nook closing member import was blocked, and the exhaust joint mouth is opened).

Controlling organization in this utility model also can be made another kind of form, form by the chute on the valve body, the slide plate that in chute, slides, screw is housed in chute, one end of spring is contained on the screw, the other end is contained in (referring to Fig. 7) on the slide plate, and the control airflow direction is when extracting the hollow nook closing member out from three-way valve, slide plate resets under the effect of spring force and covers the nook closing member import, and the exhaust joint mouth is opened.

Nut (referring to Fig. 1) is arranged on the fixing head of the present utility model, and fixing head and catheter adapter thread connection (referring to Fig. 1) can be according to patient's thoracic wall thickness adjusted depth of needle.

The thoracic-puncture needle that this utility model and present China intrathoracic surgery are commonly used is compared has following advantage:

1. skin incision is little, and hollow nook closing member front end is that cone separates Intercostal muscle and pleura passivity, and tissue injury is less, and conduit and tissue tight's applying, has reduced the chance of occurrence of subcutaneous emphysema, and is safe and reliable.

2. one step of conduit imports, and need not change and put into drainage tube, has reduced operating procedure.

3. catheter diameter is big slightly, and catheter proximal end has side opening in addition, has increased cross-sectional area, guarantees that aerofluxus is unobstructed, is difficult for being secretions, and blood clot stops up.Catheter diameter is bigger, can put into small size endoscopic observation pleura pathological changes in case of necessity, takes out biopsy of pleura, or the row cautery division of pleural adhesions.

4. drainage tube is contained on the three-way valve exhaust joint and draws from the three-way valve side, with the health keeping parallelism, is difficult for pressurized blocking-up and causes aerofluxus not smooth, and the lid of wearing the clothes is avoided patient to catch a cold by also unaffected.

5. connect with the pneumothorax case with rubber tube at hollow nook closing member indicator sub place, draw back slide plate or draw back sliding pin, put into the hollow nook closing member and get final product pressure measurement, needn't change drainage tube and connect the pressure measurement of pneumothorax case again, easy and simple to handle.

6. when hydropneumothorax, pyopneumothorax, change position or vacuum suction, on the end because of conduit side opening is arranged, cross-sectional area is bigger, can get rid of hydrothorax simultaneously.

7. can be according to patient's thoracic wall thickness adjusted depth of needle, pectoral girdle is fixed, and conduit is difficult for withdrawing from, and it is convenient to pull out pin, saves and applies section.

8. skin incision is little, needn't sew up after pulling out pin, gets final product with the involutory cut sides of maneuver, and cicatrix is little.

This utility model is applicable to intrathoracic, the surgery and the clinical treatment pneumothorax patient of tuberculosis section of hospitals at different levels.Use this utility model and treat the observed result of 50 routine pneumothoraxs: lung is not opened the person fully again, on average let the acupuncture needle remain at a certain point that the time is 619 days for every example, than the lung of domestic report (seeing " II, spontaneous pneumothorax are handled " in 1976 " CHINESE JOURNAL OF INTERNAL MEDICINE " " about handling problem of pulmonary tuberculosis complication " literary composition) fully again the average natural law water-sealed drainage bottle drain group 7～10 days of Zhang Suoxu for low.Treatment back lung is opened effective percentage 94%(47/50 again), it is 78.77%(22/28 that hydrothorax is discharged effective percentage), be better than the large size thoracic-puncture needle of use at present, relatively there were significant differences (ρ＜0.05) with the large size thoracic-puncture needle.This utility model reaches and surpasses advanced international level.
